Sonicjson runs slower on ARM than x86.

[achamilan]

Test the performance of sonicjson on x86 and ARM. The performance of sonicjson on ARM is much weaker than that on x86 and even worse than that of std json in some scenarios. What is the support for Arm? Does some feature optimization support only x86 but not ARM?

Run the test cases in the encoder directory.
go test -bench BenchmarkEncoder_Binding

<style> </style>

	X86(ns/op)	ARM(ns/op)
BenchmarkEncoder_Binding_Sonic-8	29389	85548
BenchmarkEncoder_Binding_Sonic_Fast-8	18757	65064
BenchmarkEncoder_Binding_StdLib-8	45134	58744

could you give go env output

If you're using macOS, make sure your device is plugged in and try again.
Macs slow down processing to conserve power.

It's a Linux server.

JIT is not implemented on ARM yet, so some downgrades on performance are as expected. Given that there are few ARM-CPU servers in production, it's no hurry to optimize it. Are you using sonic in an ARM-CPU production environment? If not, there is no need to pay too much attention to the difference.

We mainly use ARM-CPU. We are considering the feasibility of using sonic-json on ARM-CPU.

The primary distinction is JIT. Besides that, which of the following optimizations listed in INTRODUCTION.md are implemented in x86 but not in ARM?

JIT， which has the most siginificant effects on Encoding scenario. You can also test the Decoding performance as well, which is very close to x86
